When do children develop wisdom teeth?

Wisdom teeth usually begin developing beneath the gums during childhood, but they often do not erupt until the late teenage years or early twenties. Most wisdom teeth emerge between ages 17 and 25, although some appear later or never come through at all.

Dental examinations and X-rays can often identify developing wisdom teeth before symptoms begin. To have your teenager’s wisdom teeth evaluated, call (480) 279-5611 or schedule a dental appointment with Premier Family Dental.

What Are Wisdom Teeth?

Wisdom teeth are the third and final set of molars. They develop at the very back of the upper and lower jaws behind the second molars.

Most people can develop up to four wisdom teeth, but some have fewer. Others never develop wisdom teeth at all.

When Do Wisdom Teeth Begin Developing?

Wisdom teeth may begin forming beneath the gums and jawbone years before they become visible in the mouth. A dentist may see early signs of their development on dental X-rays during adolescence.

Development and eruption are different:

• Development refers to the tooth forming beneath the gums.
• Eruption occurs when the tooth begins breaking through the gum tissue.

This means a teenager may have developing wisdom teeth even when no tooth is visible and no symptoms are present.

When Do Wisdom Teeth Usually Erupt?

Wisdom teeth commonly erupt between ages 17 and 25. However, timing varies from person to person.

Some wisdom teeth:

• Erupt normally and become fully functional
• Partially emerge through the gums
• Remain completely beneath the gums
• Develop at an angle
• Never form at all

The absence of pain does not confirm that wisdom teeth are properly positioned. Dental imaging may be needed to assess their angle, available space, and relationship to neighboring teeth.

What Are the Signs That Wisdom Teeth Are Coming In?

Some teenagers and young adults experience no symptoms. Others may notice:

• Pressure or discomfort behind the second molars
• Tender or swollen gums
• Jaw soreness or stiffness
• Difficulty opening the mouth fully
• Food becoming trapped near the back teeth
• Persistent bad breath
• An unpleasant taste
• Pain while chewing
• Swelling near the jaw

Headaches alone are not a reliable sign of wisdom tooth eruption. A dental examination is needed to determine whether jaw or tooth symptoms are related to wisdom teeth or another condition.

What Is an Impacted Wisdom Tooth?

An impacted wisdom tooth cannot erupt normally because there is insufficient space, another tooth blocks its path, or it develops at an unfavorable angle.

Impaction may be:

• Fully impacted: The tooth remains completely beneath the gums or bone.
• Partially impacted: Part of the crown emerges while the rest remains covered.

Impacted wisdom teeth may angle toward the second molars, away from them, or lie sideways within the jaw.

What Problems Can Wisdom Teeth Cause?

Gum Infection Around a Partially Erupted Tooth

A flap of gum tissue may partially cover an erupting wisdom tooth. Food and bacteria can collect underneath it and cause inflammation or infection.

Symptoms may include pain, swelling, bad breath, a bad taste, or difficulty opening the mouth.

Tooth Decay

Wisdom teeth can be difficult to brush and floss because of their position. Partially erupted teeth may also trap food and plaque, increasing the risk of cavities.

Damage to a Neighboring Tooth

An angled wisdom tooth may press against the second molar. This can contribute to decay, gum problems, or damage to the neighboring tooth’s root or supporting tissues.

Cysts

In some cases, a fluid-filled sac can develop around an impacted wisdom tooth. A cyst may damage nearby bone, teeth, or nerves if it enlarges.

Gum Disease

The position of a wisdom tooth may make the surrounding area difficult to clean. Persistent plaque and inflammation can affect the gums around both the wisdom tooth and nearby second molar.

Pain and Swelling

An infected, decayed, or impacted wisdom tooth may cause persistent pain, facial swelling, jaw stiffness, or discomfort while chewing.

When Should Teenagers Have Their Wisdom Teeth Evaluated?

Wisdom teeth are often monitored during routine dental visits in the teenage years. The appropriate timing depends on the child’s development, symptoms, and dental history.

An evaluation may include:

• Examining the gums behind the second molars
• Checking for swelling, tenderness, or infection
• Assessing available space in the jaw
• Reviewing bite development
• Taking dental X-rays when clinically appropriate

Premier Family Dental provides comprehensive dental examinations in Gilbert to monitor developing teeth and identify concerns early.

Do All Wisdom Teeth Need to Be Removed?

No. Healthy wisdom teeth do not automatically require extraction.

Monitoring may be appropriate when the teeth are:

• Fully erupted
• Positioned correctly
• Easy to clean
• Free from cavities and gum disease
• Not damaging nearby teeth
• Not causing pain or infection

Regular examinations remain important because problems can develop later even when the teeth initially appear healthy.

When Is Wisdom Tooth Removal Recommended?

A dentist may recommend extraction when a wisdom tooth is causing or is likely to cause:

• Repeated pain or swelling
• Gum infection
• Tooth decay
• Damage to the neighboring molar
• A cyst or other jaw abnormality
• Difficulty maintaining oral hygiene
• Persistent food trapping
• Significant impaction or lack of space

The recommendation should be based on symptoms, examination findings, X-rays, age, root development, and the risks and benefits of treatment.

Can Impacted Wisdom Teeth Be Prevented?

No. The size and shape of the jaw, tooth-development pattern, and available space are largely determined by genetics and growth.

Regular dental visits cannot prevent impaction, but they can help identify it before significant pain, infection, or damage develops.

How Can Teenagers Care for Erupting Wisdom Teeth?

• Brush the back teeth carefully twice daily with fluoride toothpaste.
• Clean between the teeth every day.
• Rinse with water after meals when food becomes trapped.
• Avoid poking swollen gum tissue with fingers or sharp objects.
• Attend regular dental examinations and cleanings.
• Report pain, swelling, bad taste, or difficulty opening the mouth.

Professional teeth cleanings in Gilbert can help control plaque in areas that are difficult to reach at home.

When Is Wisdom Tooth Pain an Emergency?

Contact a dentist promptly if your teenager experiences:

• Severe or worsening pain
• Facial or jaw swelling
• Fever
• Pus or drainage
• A persistent bad taste
• Difficulty opening the mouth
• Pain that interferes with eating or sleeping

Difficulty breathing or swallowing, rapidly worsening swelling, or swelling near the eye requires immediate medical attention.

For urgent symptoms, call (480) 279-5611 or contact Premier Family Dental for emergency dental care in Gilbert.

Frequently Asked Questions About Wisdom Teeth

At what age do wisdom teeth start growing?

Wisdom teeth may begin forming beneath the gums during childhood or adolescence, but they usually do not erupt until approximately ages 17 to 25.

Can a 12-year-old have wisdom teeth?

A 12-year-old may have developing wisdom teeth visible on an X-ray, but eruption through the gums at that age is uncommon.

Can wisdom teeth come in at age 14 or 15?

It is possible, although earlier-than-average eruption is less common. A dentist can confirm whether symptoms are related to wisdom teeth.

Does everyone develop four wisdom teeth?

No. Some people develop all four, while others develop one, two, three, or none.

Can wisdom teeth remain under the gums forever?

Yes. Some wisdom teeth remain fully impacted without erupting. They may be monitored if they are healthy and not affecting nearby structures.

Do wisdom teeth always cause pain?

No. Some erupt normally without symptoms. Pain usually occurs when there is limited space, infection, decay, gum inflammation, or pressure on neighboring teeth.

Can wisdom teeth cause crowding?

Teeth can shift throughout life for several reasons. Wisdom teeth alone are not always responsible for front-tooth crowding, so removal should not be recommended solely on that assumption.

How does a dentist know if wisdom teeth are impacted?

A dental examination and X-rays can show the tooth’s position, angle, available space, root development, and relationship to nearby teeth and bone.

Is it better to remove wisdom teeth before they hurt?

Not every symptom-free wisdom tooth requires removal. The decision should be based on its position, health, future risk, and the dentist’s clinical findings.
